Both my wife and I took a recent flight from San Francisco transiting through Doha, Qatar and final destination Bangkok, Thailand. We flew onboard a new Airbus / A350-900. The first 16 plus hour leg to Doha, Qatar was smooth flying ! We were attended to by a cadre of pleasant, immaculate, and expedient flight crew/ attendants. The level of excellence surpassed all other flights regardless of Business class or economy, regardless of airline and destination spanning our five decades of flying, mostly Internationally. Each individual of the 20 or so in flight service treat us as if they individually own Qatar Airways. So inspired by such a high level of excellence. Their personal grooming is outstanding both make& female attendants. The food quality, intermediate snacks along with beverages ranks the " Best " even among the Top tier Southeast Asian carriers. And to elaborate a bit further the check-in support, fastidiousness, precautions taken during stress filled World Pandemic times was remarkable. Yes, it takes time yet we all know that everyone needs to be patient, forgiving, tolerant, etc. Finally our Doha, Qatar to Bangkok leg ( 7 hours ), we were equally Over the Top impressed and wish to thank our Pilot & 1st officer and inflight attendants, supervisors named Tiu, Nalinnipha, Apaporn, Supansa, Wichaya, Juthamas, Wansani of Flight QR 830 on Feb 7, 2021. Please forgive us for not having taken the time to identify the individuals of like character on the SFO originating flight. Gracious thanks from Mullika & I ( Greg ) Alexander for making difficult times of travel an Ultimate joy. Qatar customers for Life !!!
